BRAIDING MACHINE.

Application filed October 5, 1922. Serial N'o. 592,534.

To all 'whom t may concern:

Be it known that I, JAMES H. CoNNoLLY, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in BraidingMachines, of which the following is a speciiication.

My invention relates to braiding machines and has for its essentialobjects a more perfect control of the rotation of the bobbin to insurea. uniform tension on the yarn; to maintainthe carrier in a perfectlyvertical position and insure a smooth movement of the carrier base; andto increase the speed of travel of the carrier.

To the above tends essentially my invention `consists in such parts andin such combinations of parts as fall within the scope of the appendedclaims.

In the accompanying drawings which form a part of this specification,

Figure 1 is a side elevation, partially in vertical central section of acarrier embodying my invention as showing the wound yarn or filament inbroken lines,

Figure4, a section on line4-4'of Fig- Figure 5, a fragmentary plan Viewof the guide plate unit, showing carrier `guides therein in transversesection, and' Figure 6, a vertical section ofthe unit on line 6 6 ofFigure 5. Like reference `characters parts throughoutthe views. p Indetail my lbraider consists of a guide plate unit 10 comprising acenterplate 11, quoits "12, and outer plate 13, all arranged in the usualmanner toform a pair of sinuous vintersecting guide-channels 14 extend'ing around the unit having straight por-y tions approaching allcrossover points. In detail the plate 11, quoits 12, and plate 13 havemarginal or peripheral vertical iianges 1T, 18, and 19respectively.extending both above and below the horizontal plane of theweb portionsof the plates.` The flange 1S forms with the web portion 12of each quoit a nearly annular cavity or recess 21 from which extendpassages 22 communicating with curved horizontally disposedgrooves 2? inthe iiangel disposed upon opposite indicate like portions of the quoitperiphery. The ungrooved portions of each quoit periphery constitutelands 24 at the points of intersection of the guide channels at thecrossovers. In the passages 22 are lengths of absorbent material 25adapted to convey oil from the recess 21 to the guide grooves 23 wherebylubrication is aft'ordedto the carrier bases.

The carrier includes an oblong foot or top plate 30, a bottom plate orbase 31 having a depending central lug or stub shaft 32 for engagementwith the usual driving members. The foot land base are connected 'by twospaced posts 33 and 34 in longitu- Upon the respective posts' both forreplacements the posts usually pass.

looselythrough holes 40 in the plate 36, the bushings are a .slidingfit, and the posts provided with threads 42 to enga-ge in threadedperforations 44 in the base. The posts 33 and 34 may be integral ,withthe foot or may be fixed thereto. In this instance they are fastened bydowel pins 46 to the-foot, and are integral respectively with thespindle 48 and thread guide post 49, both of which extend through thefoot.

The portion of the foot through which the spindle passes is made with anelevation or shoulder 52, while "the post 49 extends through a thickenedportion or elevation 53.1 The foot with these, elevated portionsconstitute the body portion of the carrier.

The elevation 52 has a horizontal bore or recess 55 in which is seated ahelical spring 56 pressingat one end against the elevation or against afiller plug 57 fast thereim'and abutting with its other end against abolt 58 which presses against an arm 60 pivoted at one end to a screw G1in the foot. The

free end of the arm has an angular lateral head or finger 62.

for the purpose otpermitting ready withdrawal of the bobbin 7 5. Fast toor integral with the lower end of the sleeve or tube 67 is a base 69provided with a depending peripheral flange 70 having verticalequispaced cavities or grooves 71. The base rests upon the elevation 52or upon a. collar 7 3 upon the spindle and the liange 7.0 is adapted toenclose and engage the head 62 of the member 60. The head naturallyregisters in the grooves 71 to restrain rotation except during the takeoli operation, but the portions ot the flange between the grooves alsohave frictional contact with the head and assist in preventing racing oithe sleeve and consequent loss of tension. The bobbin 7 5 has frictionalengagement with the sleeve 67 of the bobbin carrier and rotatestherewith. The base 77 oi the bobbin has radial slots 78 to looselyreceive similarly disp sed lugs 79 on the disk 69. For the purpose ofmaintaining the bobbin in axial positi-en on the tube 67 there is fastin the latter, at a point above the spindle, a pin 31 upon which ispivoted the lower end ot a spring comprising a. vertically disposedshank 33, resilient inclined depending arm 34;, and a terminal linger85. The latter is adapted to press against the end of the bobbin.

The thread guide post 49 is rectangular in cross section and hasfastened in its upper portion a late-ral thread kguide 37, and in itsupper end a thread guide 88. Slidably mounted on the post 49 is atension weight.

`Comprising a shank V and a liange 91. Upon the latter rests a helicalspring 93 upon which rests a bearing ring 95 abutting against the threadguide 87. Upon the flange ,91 is a thread guide 97 and a lateralprojection 98. The projection engages the vertical portion 99 of anangular lever arm having an inclined upper portion 101 and whosehorizontal portion 102 is pivoted at its end upon a pin 103 fast in theportion 52 of the foot. A finger 105 on the lever portion 102 normallycontacts with the arm 60, so that as the weight in its upward travelengages the lever portion 101 the linger 105 compresses the spring 56and presses the head ot the member G0 out of engagement with its groove71 to release the disk 69.

In operation the carrier bases are impelled through thechannels la bythe usual mechanism acting upon the stub shaft 32. The bushings 317 and38 run freely in these channels, and together with the enclosed posts33, 34, and the plates 30, 31, and 30 act to restrain the carrier in anupright and nonswaying position as well as guide the same through thevarious portions of the channels. The grooves 23 accommodate the guideplate 36 through the curved portions, and this plate draws lubricatingoil from the grooves during its travel therethrough. At the straightportions of the channels adjacent the intersections, the sides of theplate 36 slide along' the lands 24k and assist in eliiecting the crossover. To further insure against deviation at the cross overs orintersections the posts 33 and 34 are so spaced as to equalapproximately the length ot the straight portion oi a channel at oneside ot the point oi' intersection ot two channels. lt will be observedthat he constituent parts ot the bases are replaceable for wear. A lessdesirable construction of the base isone in which the parts 30, 31, 3G,37 and 3S are an integral whole.

As braiding material is taken to the braiding point vot the machine itis led through guides 83, 9T and 8'? and 'thence from the bobbin.'lension is maintained in the braiding material by weight andcompression spring 93. The braiding material is led from the bobbin onsuch side as to normally lieep the notched liange 70, and therefore thebobbin, locked against the linger 62. As the braiding material is drawnoli to the braiding point the weight rises against the spring 93 and itmore material is desired to be taken oil' than can be provided by slightaction of the weight and spring said weight will rise against spring 93until it moves the inclined upper portion of the lever arm su tlicientlyto cause the finger 105 to thrust head 62 out of contact with notches inflange 70, thereby releasing the bobbin 7 5 and permitting it to rotateand cause yarn to be unwound `due to tension set up by the weight andspring 93. lmmediately as the linger 62 is removed from the notchesagainst the action ol spring 55 the latter will thrust the pawl againstthe smooth inner face of the flange 7 0, and thereby cause a frictionwhich will restrain flange 7 0 and consequently the bobbin from too freea rotation, and consequent loss oit' tension in the thread.

It is intended that all matter contained in the above description orshown in the accompanying drawings shall be interpreted as illustrativeand not in a limiting sense.

I claim 1. In a braiding machin-e, a guide plate unit provided withsinuous intersecting channels, and with peripheral grooves opening intothe channels, and a carrier base comprising posts slidablv mounted inthe channels, plates upon the ends of the posts, and a guide platecarried by the posts registering in the grooves.
